Comcast Using Packet Injection To Push Its Own Ads Via WiFi, Apparently Oblivious To Security Concerns
from the because-it's-comcast dept
A Comcast spokesman told Ars the program began months ago. One facet of it is designed to alert consumers that they are connected to Comcast's Xfinity service. Other ads remind Web surfers to download Xfinity apps, Comcast spokesman Charlie Douglas told Ars in telephone interviews.It's a courtesy to hijack the page a person asked for and insert something that no one asked for on it? I don't think so. There's a reason that packet injection is considered an attack and a security risk -- and it's got nothing to do with courtesy.
The advertisements may appear about every seven minutes or so, he said, and they last for just seconds before trailing away. Douglas said the advertising campaign only applies to Xfinity's publicly available Wi-Fi hot spots that dot the landscape. Comcast customers connected to their own Xfinity Wi-Fi routers when they're at home are not affected, he said.
"We think it's a courtesy, and it helps address some concerns that people might not be absolutely sure they're on a hotspot from Comcast," Douglas said.
Certainly, the website that Singel was browsing when he spotted it, Mediagzer, was not pleased about having its own site hijacked and defaced:
"Indeed, they were not ours," Gabe Rivera, who runs Mediagazer and Techmeme, said in an e-mail. In another e-mail, he said, "someone else is inserting them in a sneaky way."Kravets also talks to Robb Topolski, the guy who first provided the evidence to show that Comcast was throttling BitTorrent a while back, kicking off one of the first big net neutrality fights (which resulted in the FCC slapping Comcast's wrists). Topolski notes that what they're doing here is technically equivalent:
"It's the duty of the service provider to pull packets without treating them or modifying them or injecting stuff or forging packets. None of that should be in the province of the service provider," he said. "Imagine every Web page with a Comcast bug in the lower righthand corner. It's the antithesis of what a service provider is supposed to do. We want Internet access, not another version of cable TV."
